Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.

Chiral symmetry breaking for large "Nf" and the properties of the "rho" meson near the conformal window

This paper investigates how the ground-state properties of the ρ\rho meson evolve as the number of light-quark flavors (NfN_f) approaches the conformal window, revealing that while chiral symmetry restoration and deconfinement occur at a critical flavor number, the ρ\rho meson's survival is governed by the divergence of the confinement length scale rather than mass crossing, resulting in a larger, rounder object with flattened form factors and an expanding charge radius.

Probe of Solar Neutrino Magnetic Moments through Spin-Flavor Precession: Resonance Structure and Antineutrino Appearance

This paper investigates solar neutrino spin-flavor precession within a three-flavor framework, demonstrating that while resonant conversions are suppressed, nonresonant Majorana conversion offers a distinctive antineutrino signal that the Jinping Neutrino Experiment could detect to set stringent new limits on neutrino magnetic moments.

NICER neutron stars with dark energy and dark matter: effects on the inferred equation of state

This study utilizes Bayesian inference on NICER mass-radius data to demonstrate that while dark energy cores significantly alter and can be constrained by neutron star observations, asymmetric dark matter cores remain observationally indistinguishable from purely baryonic stars for mass fractions up to 5%, implying that mass-radius measurements alone are insufficient to detect the latter.

Emergent Einstein-Cartan gravity from a spinor loop

This paper demonstrates that in Einstein-Cartan spinor gravity, spinor loops generate the kinetic and mass terms for both the local-Lorentz gauge field and the vierbein, thereby inducing a complete effective action comprising a cosmological constant, Einstein-Hilbert term, Weyl-squared term, and torsion dynamics that respects general-coordinate and local-Lorentz gauge invariances.

Interpretation of the excited Ωc\Omega_c family via mass and width in the chiral quark model

This study utilizes the chiral quark model combined with the 3P0^3P_0 decay mechanism to provide a coherent interpretation of the low-lying Ωc\Omega_c spectrum, successfully identifying most observed states as λ\lambda-mode 1P1P excitations while suggesting that Ωc(3119)\Omega_c(3119) is not a pure three-quark state and assigning Ωc(3185)\Omega_c(3185) and Ωc(3327)\Omega_c(3327) to 2S2S and 1D1D configurations, respectively.

Stability and Structural Properties of Hot Quark Stars within Perturbative QCD

This paper develops a thermodynamically consistent equation of state for hot strange quark matter incorporating perturbative QCD corrections up to O(αs)\mathcal{O}(\alpha_s) and finite-temperature effects, demonstrating that such configurations are absolutely stable and can support compact stars with masses exceeding 2 M⊙2\,M_\odot in agreement with current astrophysical observations.

Boosted or Inelastic? Discriminating Interpretations of the LZ 248 keV Event

This paper proposes that the single 248 keV nuclear recoil event observed by the LUX-ZEPLIN experiment can be explained by either endothermic inelastic dark matter or boosted dark matter, demonstrating that these two scenarios are spectrally distinguishable across different effective operators and can be definitively resolved with additional data from the full LZ exposure.

Probing the CPT Constraint on CP Violation with B+→π+μ+μ−B^+ \to\pi^+ \mu^+ \mu^- Decay

This paper presents a theoretical framework derived from the CPT theorem and S-matrix unitarity to distinguish between inclusive and exclusive mechanisms of CP violation, proposing that a precise measurement of the integrated CP asymmetry in the B+→π+μ+μ−B^+ \to \pi^+ \mu^+ \mu^- decay can unambiguously discriminate between these two scenarios.

Inelastic Dark Matter at LZ from Radiative Dirac Neutrino Mass Paradigm

This paper proposes a radiative Dirac neutrino mass model with a specific scalar and fermion sector that naturally generates the off-diagonal nucleon coupling required to explain the high-energy LZ230616 event via inelastic dark matter scattering, while simultaneously accounting for neutrino masses, the observed relic abundance, and existing experimental constraints.
